IMPROVEMENT IN OSCILLATING ENGINES.

Specification forming part of Letters Patent N0.15S,93S, dated January 19,1875; application led December 5, 1874.

To all whom it may concern: Y

, Beit known that I, GEORGE W. HEALD, of Baldwinsville, Onondaga county, New York, have invented new and useful Improvements in Oscillating Engines, of which the following l is a specification:

My improvement in oscillating engines consists of a novel contrivance of tightening bearings and adjusting-screws therefor with the crosshead of the'piston-rod, which is arranged in guides projecting from the cylinder-head, to take the strain of oscillating the cylinder from the rod. y

Figure l is a side elevation of my improved engine. Fig.2 is a plan view. Fig. 3 is a side elevation of the cross-head and adjusting keys pipes will be attached to these stationary trunnions, which thus form substantial and simple connections for the pipes with the oscillating trunnions. They are bolted t0 the bearings E, to prevent being turned by the oscillating trunnions. F represents the cross-head of the piston, carrying the boxes Gr for the crank H, and working in the guides I, to relieve the piston-rod ot' the strain of oscillating the cylinder J, and K represents the bearings ofthe cross-head in the guides. These bearings are also contrived to serve as tighteningkeys for taking up the slack by means ot' the inclines L on them, and the corresponding reverse inclines on the cross-heads, and they are connected to the stud-screws M projecting from the cross-head, and provided with adjustingnuts N, by which they are forced in 'and out, as may be required; but other meansof adjusting them may be employed.

Havingthus described my invention, I claim as new and desire to secure by Letters Pat` ent- 'Ihe combination ofthe wedgeshaped bearings, stud-screws M, and adjusting-nuts N, with the cross-head F and the guides I of an oscillatin g engine, substantially as specified.
